What's Facebook's secret? Company tells all today

SAN FRANCISCO (AP) — Facebook’s mystery “press event” Tuesday could reveal a more robust search feature that would intensify the competition between the social networking giant and rival Google Inc.

Facebook is holding the event at 10 a.m. (1 p.m. EST) at its Menlo Park, Calif., headquarters. The company has not said what it plans to announce. Last week, it invited bloggers and journalists to “come see what we’re building.”

The company probably won’t be showing off a new office building. It’s also unlikely to unveil a much-rumored “Facebook phone” —unless CEO Mark Zuckerberg has changed his mind recently. Last fall, he shot down speculation that Facebook was building its own smartphone.

Since the company’s current search functions are limited, users would likely welcome a better way to search Facebook.
